I 0 .aZZ whom it may concern:

Be it known that I, CHARLES P. R. Trr nL, a citizen of the United States, and a resident of North .Andover, county ofEssex State of Massachusetts (whose post-oliice address is Prescott Street, North Andover, vlVIass.) have invented an improvement in Viarp Compressors, of which the following 'descriptlon, in connect on w th the accompanying draw ng, is a specification, like characters on the drawing representing like parts.

7 This invention relates to mechanism for compress ng the warp Cltillllg the beaming operation.

The object of theinvention is to provide a-warp compressor so constructed as to pro ducean equal uniform and opposite rolling pressure against the warp mass on the beam as it increases in diameter.

The object of the invention is further to eliminate the disadvantages arising fromapplying compression to the warp beam at one side only.

The object of the invention is further to insure during the compression the maintenance of a perfectly cylindrical and compact warpmass on the beam.

The object of the invention is further to presapplied to the warp beam by mean sure applied .at opposite sides in eqn amounts and, therefore. producing no in terial strain on the warp beam or the gadgeon thereof.

The object of the invention further to provlde a warp. compressor having a pair of compression rolls rotarily mounted in supports movable toward and from the beam at oppositesides thereof with means connecting the supports and acting as the rolls are forced apart by the increasing diameter of the warp mass to cause the rolls to main tain an equal, uniform and opposite pressure against the Warp mass.

The object of the invention is further to provide novel 'means for securing and adjusting the amount of the pressure applied by the compression rolls to the beam at opposite sides thereof.

The object of the invention is further to provide in a singlennit a combined warp beam and compressor embodying the inventionsupported onia movable frame whereby the entire unit may be moved from place to place as required.

to and towardand from the axis of the warp beam at opposite sides thereof and acting to maintain .an 7 equal uniform and "opposite pressure of the rolls against the Warp mass on the beam and so arranged that the rolls may be adjusted longitudinally to enable a warp mass of greater length than the rolls to be compressed.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly set forth in the claims. i I V In the drawings; 7

It is frequently desirable that warp when it is wound upon a beam for use in. a'loom or other textile machine shall becompressed into a compact mass. When this is done it is necessary that the warp mass shall be uniformly, compressed throughout during the winding operation of the warp. upon the beam and it is necessary that the warp mass shall be perfectly cylindrical throughout. If the warpbeam springs duringthe compressing operation owing to unbalanced pressure then the warp mass departs from the cylindrical form, the warp is not com-- ressed evenly and highly undesirable results are obtained in the subsequent handling of the warp.

In the present invention the compression is applied in opposite directions to opposite sides of the warp beam so that there can be no tendency to spring or distort the warp beam or its gudgeons and consequently the pressure is applied to the warp beam evenly and uniformly throughout. Furthermore the pressure by means of this invention may be adjusted to any desired amount so as to produce any desired compactness in the mass of warp as it is wound on the beam. The drawings illustrate a simple practical and preferred form of mechanism for securing these essential results. The mechanism illustrated also contains many fea tures of novelty in the more or less specific means by which the broad features of the invention are securec.

A warp beamer of a generally familiar type is illustrated. This device comprises 7 a frame 1 in which is mounted a shaft 2 of the frame.

carrying a large internal gear 3'at one side One end of the gudgeon of a warp beam at has a bearing in a socket at the end of the shaft 2 while studs project from the face of the gear 3 into recesses in the adjacent head 6 of the beam. Thus rotation of the shaft 2 imparts rotation to the warp beam. The gear 3 is rotated. by a train of gearing from a suitable source of power as a belt running over the fast and loose pulleys 7 It is essential that the opposite end of the warp beam gudgeon shall be supported in alignment with the shaft 2 and that the warp compressing; mechanism shall be sup ported in accurate defined relation to the warp beam. These mechanisms may be all mounted upon the floor in the required posi- 'tion but, as involving a further feature of the invention. the entire mechanism is il lustrated in Fig. 1 as supported by a single movable rigid frame. This frame 8 which may be of any suitable construction has mounted thereon and depending there beneath journal brackets 9 in which are jouc nailed the supporting rollers 10. These rollers in turn are shown for convenience running on tracks 11 thus enabling the entire beaming andcompressing mechanism to he moved from place to place in the mill as may be required.

The frame 1 of the warp beamer is shown as bolted at 12 to the movable frame 8. At the opposite end. the supporting stand 13 mounted in fixed relation on the warp compressor and thereby is mounted on the movable frame 8. This supporting: stand 13 presents an open bearing in which the end gudgeon 14.- is journalled in accurate alignincense ment with the shaft 2. A guide roll or bar 15 tor the warp is mounted parallel to and above the warp beam, one end resting in a bracket 16 onthe frame of the beamer anl the other end in an open bearing 17 at LJ' top of the outer supportin stand 13.

In the preferred form of the invention illustrated the required rolling pressure is imparted to the warp mass being wound on the warp beam at opposite sides thereof by a pair of freely rotatable compression rolls 18 and 19. Each of these rolls is rotarily mounted in a suitable support movable to ward and from the axis of th warp beam so to maintain each compression roll in parallelism with the said axis. Preferably each compression roll is mounted in a set comprising a plurality of similar supports and preferably also each of these supports secures its movement toward and from the warp beam by being pivotally mounted at its lower end beneath the warp beam so as to swing toward and from the warp beam. An opposite pair of the supports for the compression rollers is shown in side sie e tion in Figure 3. The supports 20 carrvi the compression roll 19 are secured lower ends to a shaft 21. extending parto the axis of the warp beam and having its hearings in suitable supporting brackets extending transversely of the machine and. as illustrated. bolted at to the main frame 8. ln a similar manner the su g'iports 2% carrying. the rompression roll mounted on a similar shaft 25. Thes 21 and 25 their outer ends are joi. i in an outer transverse bracket 26 also. as illustrated, bolted at 27 to the main frame 8, the outer ends of these shafts serve a convenient means for supportingthe outer stand 13 and insuring its accuracy of position. The stand may. therefor .dilv adjusted longitudinally of the sh" fts to provide for different leng hs of warp beams.

The number and t e pacing of the supports 20 and 24 of the respective sets of supports will vary according to the particular requirements. Four such si )ports are illustrated in each set as being for the ordinary run of work. Each compression roll is jouri'ialled in recess 28 in each support and rests upon anti friction rolls 29 journalled on axle 31 and 32. The axle 30 extends throi and is common to the uppermost anti tion roll 29 of each set of supports so form a guard to prei- 'cnt the operator or clothing being caught and drawn in b tween the compression roll and the warp beam. Such a guard is particularly importaut at the front of the compressor where the contacting peripheries of the. warp mass and the compression roll are moving down wardly.

While it is desirable that the compression icie rolls 18 and 19 acting at opposite sides of the warp beam shall each be of substantially the length of the warp mass being Wound upon the beam still the desired results can be secured and a substantial degree of adjustment permitted by this invention to compress beams of varying length. This adj ustability is secured by providing for the relative longitudinal adjustment of the compression rolls in their supports. Thus by adjusting one compression roll in one direction and the other in the opposite direction the desired equality of opposite pressure may be'secured on a beam, the warp mass of which has a grelater length than that of the compression rol s.

In the illustration the warp beam is shown as provided with false heads'33 of a familiar type positioned on the warp beam at a greater distance apart than the length of the compression rollers 19 and 20. To take care of this condition the compression roll 19 is'adjusted longitudinally, for example to the left, until its end comes against the false head 33 at the left while the opposite compression roll 20 is adjusted to the right until its end comes against the false head at the right. Thus pressure is produced over the entire warp mass and with entirely satisfactory results. Suitable gauges are provided for positioning and holding the compression rolls in longitudinal adjusted position to prevent them from creeping away from the heads. As illustrated similar gauges each comprising a shank 34 and a head 35 are mounted in and longitudinally adjustable of each of the endmost supports of each set of supports. They are each locked in place by a suitable set screw operated by a handle 36. In the adjustment illustrated in Fig. 2 the gauge at the right hand end of the compression roll 19 will be positioned so as to extend over the right hand end of the roll and hold it between the head 35 of the gauge and the false head 33 of the beam at the opposite end. In a similarmanner the gauge at the left hand end of the compression roll 20 will be positioned to hold that roll with its right hand end against the false head 33 at the right hand end of the beam. Thus any two or all of the gauges may be used according 'to the particular conditions.

Novel and efficient means are provided by this invention for maintaining the required equal uniform and opposite pressure of the compression rolls on the warp mass as it increases in diameter and forces the rolls apart. As the supports of each set carrying the compression rolls move simultaneously and to the same extent the required force is conveniently applied to a single element and distributed therefrom to the supports at one side and from these to the supports at-the opposite side.

In the construction illustrated a shaft 37' extending parallel With the compression roll 19 and the shaft 21 is journalled in the supports 20 of the set at the front of the machine. Rotation of this shaft 37 is retarded by a friction let-off mechanism, the preferred form of which is shown in detail in Fig. 4. For this purpose a friction drum 38 is splined at 39 to the shaft 37. The periphery of this drum is clasped by a two part clamp. The parts .40 and 41 of this clamp are substantially semi-circular and are provided at their inner face with a friction facing 42 of leather or other suitable material. At one side of the drum these parts are hinged together as by the bolt 43 having a loose fit therein while at the opposite side the clamp parts project to form arms 44 and 45. The arm'44 at its lower end is conveniently'journalled on the shaft 21. The required friction between the clamp and the drum is secured and adjusted in amoimt in a novel andetiicient manner. A spring 46 preferably of a comparatively .heavy leaf form abuts the outer face of the arm 44 and a bolt 4'? is provided which extends transversely of and connects the arms 44and 45. This bolt at its outer end is provided with a pair of lock nuts 48 engaging the outer face of the spring 46' through which the bolt also passes. At its inner end the bolt is connected to the arm so as to be longitudinally adjustable thereof. As a simple means for securing this adjustment the inner end '49of the bolt is ournalled on a pin 50 which is eccentric to the stud 51 journalled in the lower end of the arm 45. A handle 52 pro sets from theshaft 51 to within reach of the operator. Consequently by moving the handle 52 up or down the position of the eccentric pin 50 is changed to release or apply the friction between the clamp and the drum and by adjusting the nuts 48 on the bolt the amount of the friction is controlled. A stop 53 in the form of a collar is secured to the bolt 47 on the opposite side of the arm 44 from the spring 46 and is so positioned that when the handle 52 is moved to release the friction on the drum this stop engages with the face of the arm 44 and neutralizes the ction of the spring 46.

In order that the friction on the drum may-not be entirely released but that a light friction may still be maintained between the clamp and the drum an auxiliary bolt 54 is provided extending through the arms 44 and 45. A relatively light spring 55 surrounds this bolt between the arm 45 and a hand nut 56 on the end of the bolt. Hence the spring may be adjusted to give the required light holding friction when the main friction on the drum is released.

The shaft 37 carries adjacent each supp'ort20 at one'side thereof ananchor socket Hit) and at the other side thereof a. drum for a flexible connector such as a wire cable. The anchor socket 57 is loose on the shaft while the drum 58 is splined at 59 thereto. The drum at one side is provided with a flange 60 and at the other side with a hub 61 over which fits a tallen collar 6 This collar is held in any desired position of rotary adjustment with respect to the drum by a set screw 63 passing through the collar and abutting the hub 61.

The opposite support j journalled thereon an idler roll 6&- and beneath the warp beam a pair of guide rolls 65 and 66 are journalled on a shaft 67 mounted intermediate the shafts 21 and 25 in the supporting brackets 22.

The flexible connector employed must be of a substantially non-stretchable character and of great strength. For this purpose a suitably formed wire cable 68 is illustrated. @ne of these cables is provided for each pair of supports 20 and 2d. The cable at one end is firmly secured in the anchor socket 5?. From thence it passes beneath the guide roll 65 up around the idler 64. on the opposite support down beneath the guide roll 66 and thence around the drum 58 to which the end is secured by means of the talre-up collar 62. For this purpose the end is threaded through an aperture in the collar and firmly locked by the set screws 69. Protection against injury to the operator is had by suitable guards wherever necessary and such a guard is shown at 70 surrounding the idler 64L. This idler has its plane of rotation pointing in the general direction of the lower portion of the periphery of the guide rolls 65 and 66 but. as the angle of this plane changes somewhat the supports move apart deflecting guide olls 71 are journalled on the support 24 oeneath the connector 68 and adjacent the idler 6% thus preventing any binding of the idler 64. The flexible non-stretchable con nector such as the wire cable 68 forms a very efficient means for securing equality in the pressure exerted by the compression rolls at the opposite sides of the warp beam. The take-up collars form a simple and efadjusting each connector 2d of each. pair has festive means or so that the force exerted by of each pair may be the same. All that it is necessary to do is to loosen the set screw 63 and wind. or unwind the collar 62 on the drum 58 until the connector in each case pulls the supports together with the same amount of force.

After the several flexible connectors have been tightened up to produce a uniform pressure, the amount of compression exerted by the compression rolls on the warp mass on the beam is determined by the friction let-off already described and is under perthe supports feet control of the operator. lly shifting the handle 52 the amount of this friction is varied being greatest when the handle is in the lowermost position and gradually diminished until the handle reaches the uppermost or releasing position. In addition by varying the number of leaves of the spring :6 and by adjusting the nuts on the bolt ll there is no practical. limit to the amount of con'ipression that may be applied and as the force exerted by each compression roll is opposed by that exerted by the other through the medium of the connector there can be no inju done to tl warp beam or its gudgeon, no springing oi" the warp beam, and the winding of a li compacted cylindrical mass of warp on the beam is assured.

The supports are separated to permit the removal of the beam after the beaming operation is completed and brought together again after the fresh beam is placed in position by a pawl and ratchet mechanism shown in detail in Fig. A sleeve is secured at a convenient point to the shaft 37. This sleeve carries rigid therewith two ratchet wheels 73 one having the teeth pointing in one direction and the other hav ing the teeth pointing in the opposite direction. Between the ratchet wheels and on the sleeve is journalled a pawl carrier E i having a socket in which may be insert ed a handle 7 This pawl carrier carries pawls 76 co-operating with one ratchet wheel and 7'7 co-operating with the other. A spring 78 extends from the pawl carrier T l down to a collar 79 on the shaft 21 or to some convenient point at the bottom of the machine and serves to counterbalance the pawl carrier and maintain it normally in upright position. It will thus be seen that by throwing the proper pawl into engageinent with the proper ratchet wheel and rocking the handle 7 5 the shaft 37 may be rotated in either direction. Consequently at the end of the beaming operation the handle 52 is thrown to releasing position leaving the light friction, resulting from the spring 55, on the let off mechanism and the shaft 37 is then rotated to unwind the drums 58 and allow the supports to move apart. I

The latches 80 are pivoted at an intermediate point as for example on the shaft 67 between each pair of supports and provided with hooks 81 adapted to catch on studs 82 on the supports and hold the supports in open position. If it necessary to open the supports further to re move a warp beam wound with very large mass of warp or for any other purpose they may be allowed to swing way apart and even down to the floor. As these supports with the compression rolls are quite heavy a counterbalance is provided therefor er.

erting its main effect after the supports,

swing so as to carry their center of gravity past the axes of the shaft 21 and 25 respectively. This counterbalancing mechanism is shown in the form of coiled compression springs 83. Each spring is provide with a loop-shaped member 84; which is secured at an intermediate point beneath the warp beam as by engaging over the shaft 67, passes through the spring 83 and hooks over the outer end thereof at Each spring is also engaged at its inner end by a hooked rod 86 connected at its outer end to a chain 87 extending about the periphery of, and secured by a bolt 88 to, a collar 89 secured to the shaft carrying the support. These counter balancing springs can be located at any desired positions and they can readily be so proportioned and arranged that the heavy weight of the supports and compression roller is substantially counterbalanced and no excessive force is required to lift the supports back to operative position or to a position where they may be brought together by the pawl and ratchet mechanism.

When, therefore, the operator by means of the handle 52 releases the main friction on the drum, the two sets of supports carrying the compression rolls are readily moved away from the beam or toward the beam by operating the handle 75.

In Figure 7 a warp compressor embodying the invention is shown mounted inclependently of the beamer so as to constitute a single portable unit. In this form the entire mechanism .is mounted on a rigid frame 90, the various supporting parts such as the brackets 22 and 26 being bolted to this frame. This main frame 90 in turn is illustrated, for convenience, as carried by a supporting frame 91 having the depending brackets 92 in which are journalled the supporting rollers 93. This warp compressing unit may, therefore, be pushed about upon the floor or upon tracks tobring it into alignment with a suitable beamer.
